Background. Chemotherapy is a therapeutic modality for elderly with cancer which can pose elderly, especially frail patients, to fatal side effect. To date, there is no prediction model incorporating frailty in clincal practice. This study aims to develop prediction model which includes frailty state evaluation in predicting severe chemotoxicity in elderly. Methods. A retrospective cohort study using secondary data of elderly underwent chemotherapy during 2019-2021 was conducted in Cipto Mangunkusumo Hospital. Data of determinants ( sex, age, polypharmacy, frailty status, nutritional status, depression, cognitive status, cancer type, polychemotherapy, and functional status) and the incidence severe chemotherapy side effect according to grade 3-5 CTCAE were collected. Data was analyzed to develop prediction model with Cox regression using SPSS Results. Of 193 subjects, most of them are male, with median age of 65.6 (IQR 60-82) years old. Severe chemotoxicity was found in 36% of the subjects. Prediction model consists of polypharmacy, number of chemotherapy drugs, cancer type and frailty status was developed. The model has AUC of 0.79 (95% CI 0.70-0.88), p value 0,01 Conclusion. A prognostic Model consists of polypharmacy, number of chemotherapy drugs, cancer type and frailty status can predict incidence of severe chemotoxicity in elderly with AUC 0.79 (95%CI 0.70-0.88)
Background: There was still limited data whether sarcopenia related to chemotherapy toxicity and impacted to quality of life. The aim is to know the role of sarcopenia on chemotherapy toxicity and changed of quality of life after breast cancer patients. Methods: This prospective cohort study was conducted in breast cancer women patients with age 18 to 59-year old who underwent chemotherapy, will be evaluated sarcopenia with Bio-Impedans analysis and JAMAR dynamometer. Evaluation of chemotherapy toxicity and quality of life with National cancer institute common toxicity criteria and European Organization for research and treatment of cancer care quality of life 30 and BRE-23. Results: A total of 128 breast cancer subjects with median age 47(25-59) year old, 39.1% with obese, 56.3% with stage 2 disease. Sarcopenia before chemotherapy associated with toxicities after first, second, and third cycles of chemotherapy with adjusted OR 1.73(0.62-4.86); 40.34(2.54-641.19); and 3.98(0.14-114.01), respectively. Sarcopenia associated with changed of quality of life scores of loss of appetite, constipation, and financial loss domains with adjusted OR 2.23(0.27-18.63), 3.42(0.75-15.50), and 5.50(1.41-21.42) respectively after underwent three cycles of chemotherapy. Conclusion: Sarcopenia before chemotherapy associated with chemotherapy toxicity and decreased quality of life score for several domain of symptom scales
ABSTRAK
Lean Thinking, filosofi manajemen yang berfokus pada proses usaha, merupakan metode yang tepat untuk menganalisis alur proses pengadaan obat kemoterapi di RS MMC Jakarta. Penelitian ini mengaplikasikan prinsip Lean dalam menggambarkan alur proses yang terjadi saat ini, menganalisis masalah, serta mendesain alur proses yang lebih ideal. Metode yang dilakukan adalah penelitian kualitatif, dengan observasi langsung proses yang terjadi, wawancara mendalam dengan staf terkait, serta telaah dokumen. Hasil penelitian menunjukkan bahwa pada saat ini sebagian besar pengadaan obat kemoterapi di RS MMC saat ini berlangsung secara cito tanpa standar yang khusus, sehingga polanya tidak jelas. Masalah utama yang ditemukan adalah seringnya obat tidak ada di distributor utamanya dan proses koordinasi antar-unit yang rumit apabila hal ini terjadi. Alur proses terdiri dari 48 kegiatan pada proses pengadaan obat kemoterapi di RS MMC dan hanya 18% dari waktu prosesnya yang bersifat value-added. Analisis masalah dilakukan dengan menggunakan Lean Tools Value Stream Mapping (VSM), identifikasi 8 wastes, analisis akar masalah dengan metode 5 Whys, Kanban, serta konsep error-proofing. Setelah analisis akar masalah dan perumusan ide perbaikan, dilakukan desain ulang yang menghasilkan alur proses baru, terdiri dari 16 kegiatan, dengan persentase waktu value added mencapai 83%.
ABSTRACT
Lean Thinking, a management philosophy focusing on business processes, is the right method to analysis the chemotherapy drugs purchasing process at MMC Hospital Jakarta. This study applied Lean principles in mapping the current work process, analyzing problems, and redesigining a more ideal work flow. Research method used in this study is qualitative approach, by doing direct observation of the actual process, in-depth interview with staffs involved, and document study. This research showed that the current chemotherapy drugs purchasing process are done cito with no specific standard, therefore there was no clear pattern. The main problems were often not found at the main distributors, and that it would demand a very complicated coordination process. The current work process consisted of 48 activities, and only 18% of the total process time was value-added. Analysis were done with the use of Lean Tools Value Stream Mapping (VSM), 8 wastes identification, root cause analysis with 5 Whys method, Kanban, and error-proofing concept. After conducting root-cause analysis and comprising improvement ideas, a new work process was designed, consisted of 16 activites, with 83% value added time.
Latar belakang. Demam neutropenia merupakan salah satu adverse event yang sering terjadi pasien kanker payudara. Demam neutropenia yang tidak dapat dicegah dan ditangani dengan baik mengakibatkan komplikasi, kematian dan mempengaruhi efektivitas pengobatan. Olehkarena itu perlu diketahui faktor-faktor dominan apa saja yang dapat mempengaruhi terjadinya demam neutropenia agar kejadian demam neutropenia dapat dicegah. Tujuan. Untuk mengetahui hubungan variabel bebas usia, status performa, penyakit penyerta, jenis kanker payudara, stadium kanker payudara, pemberian kemoterapi sitotoksik, albumin, hemoglobin dengan kejadian demam neutropenia pada pasien kanker payudara di RS Kanker Dharmais Jakarta. Metode. Penelitian ini merupakan penelitian observasional dengan desain potong lintang. Hasil. Proporsi demam neutropenia adalah 13,67%. Faktor risiko dominan penyebab demam neutropenia adalah variabel status performa pasien PR Crude 3,64 (95% CI 2,07-6,39, p-value 0,001), PR Adjusted 2,16 (95% CI 1,09-4,30, p-value 0,027); diabetes PR Crude 2,30 (95% CI 1,21-4,53; p-value 0,012), PR Adjusted 2,17 (95%CI 1,07-4,41; p-value 0,030); stadium tiga PR Crude 2,28 (95% CI 1,2-5,07; p-value 0,001) PR Adjusted 2,49 (95% CI 1,11-5,60; p-value 0,001), dan stadium empat PR Crude 3,93 (95% CI 1,72-8,97; p-value 0,001) PR Adjusted 3,6 (95% CI 1,45-8,93; p-value 0,001). Kesimpulan. Kejadian demam neutropenia pada pasien kanker payudara menunjukkan hasil yang signifikan. Upaya pencegahan menggunakan profilaksis G-CSF diperlukan untuk pasien dengan risiko tinggi mengalami demam neutropenia. Penelitian lanjutan terkait konsekuensi demam neutropenia perlu dilakukan. Kata kunci. Demam neutropenia, faktor risiko, kanker payudara, kemoterapi sitotoksis
Background. Febrile neutropenia is one of the adverse events that often occur in breast cancer patients. If it cannot be prevented and treated properly, it increases complications and mortality and decreases the effectiveness of treatment. Therefore, knowing the dominant factors that can affect febrile neutropenia is necessary, and febrile neutropenia can be prevented. Objective. To determine the relationship between independent variables of age, performance status, comorbidities, type of breast cancer, stage of breast cancer, regiment of cytotoxic chemotherapy, albumin, and hemoglobin with the incidence of febrile neutropenia in breast cancer patients at Dharmais Cancer Hospital, Jakarta. Method. Observational study with cross-sectional design. Results. The proportion of febrile neutropenia was 13.67%. The dominant risk factors causing febrile neutropenia are patient performance status PR Crude 3,64 (95% CI 2,07-6,39, p-value 0,001), PR Adjusted 2,16 (95% CI 1,09-4,30, p-value 0,027); diabetes PR Crude 2,30 (95% CI 1,21-4,53; p-value 0,012), PR Adjusted 2,17 (95%CI 1,07-4,41; p-value 0,030); stages three of breast cancer PR Crude 2,28 (95% CI 1,2-5,07; p-value 0,001) PR Adjusted 2,49 (95% CI 1,11-5,60; p-value 0,001); stage four of breast cancer PR Crude 3,93 (95% CI 1,72-8,97; p-value 0,001) PR Adjusted 3,6 (95% CI 1,45-8,93; p-value 0,001). Conclusion. The incidence of febrile neutropenia in breast cancer patients showed significant results. Prophylaxis G-CSF is needed for patients at high risk of developing febrile neutropenia. Further research related to the consequences of febrile neutropenia is required. Keywords. Breast cancer, cytotoxic chemotherapy, febrile neutropenia, risk factors
